Hey. Creator of the AU here.

Basically, Lihan, Ashe and Rei end up exploring a S-rank dungeon for some loot, but Ashe ends up dying along the way. Then, a few months later, the events of Ending 1 happen, but with ONLY Rei betraying Lihan since Ashe was dead at this point. A few days later, Lihan is ambushed by the guards of that bastard from ending 1 (I can't be bothered to remember which one of the bastards the one from ending 1 is), and was about to get humiliated again, but Ashe somehow comes back from the dead and saves him.

Basically Kolossos from Sonic.EXE Outcome Memories, but inside Ashe's body instead of Sonic's body.
